java - 无法实现图像裁剪

Question

当我同步 API 'com.theartofdev.edmodo:android-image-cropper:2.8.+' 时，它会强调实现 'com.android.support:appcompat-v7:28.0.0':

enter dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:cardview-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:support-v4:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.android.support:gridlayout-v7:28.0.0'
    api 'com.theartofdev.edmodo:android-image-cropper:2.8.+'


}

您的用例是什么？你有什么格式的图像？ (位图、Uri 或位于 blob 存储中)为什么不调整图像大小而不是裁剪？

如果图像位于位图中，这里是调整大小的代码(如果有帮助的话)

 /**
 * reduces the size of the image
 * @param image
 * @param maxSize
 * @return
 */
fun getResizedBitmap(image: Bitmap, maxSize: Int): Bitmap {
    var width: Int = image.width
    var height: Int = image.height

    val bitmapRatio: Double = (width / height).toDouble()
    if (bitmapRatio > 1) {
        width = maxSize
        height = (width / bitmapRatio).toInt()
    } else {
        height = maxSize
        width = (height * bitmapRatio).toInt()
    }
    return Bitmap.createScaledBitmap(image, width, height, true)
}
